I do not deny that is can be considered as a flaw,
i would just reword your sentence a little bit:
I don't need to do this with SunOS 4.1.x. If GNU tar is not able to handle
this properly it's a big flaw.
I had a quick look at the GNU tar source and if the size (-L <size>)
is not specified but -M is, it relies on getting either ENOSPC or EIO
or ENXIO error and will ask for a new volume if it got such an error
or it will otherwise choke out (writeerror() does an exit()).
/* We're multivol Panic if we didn't get the right kind of response */
/* ENXIO is for the UNIX PC */
if (err < 0 && errno != ENOSPC && errno != EIO && errno != ENXIO)
So, my guess would be that the floppy driver does not return the correct
Am I right ? Could the floppy driver author confirm this ?
